Encapsulation of direction management of neighbors for a 3D 26-neighborhood.

## Member Enumeration Documentation

enum Direction

provides enumeration of all directions. DirectionCount may be used for portable loop termination conditions.

Equivalent to `diff(static_cast<Direction>(code))`. (note: there is no bounds checking on the code you pass.)

static bool isDiagonal | ( | Direction | dir | ) | `[static]`

Check whether a code refers to a diagonal direction. Useful if you want to abstract the differences between 6- and 26-neighborhood. Always `false` for 6-neighborhood.

static Diff3D const& left | ( |  | ) | `[static]`

Offset to the left neighbor

static unsigned int nearBorderDirectionCount | ( | AtVolumeBorder | b | ) | `[static]`

|  | int | index |
| ) |  |  | `[static]`

The valid direction codes when the center is at the volume border. index must be in the range `0...nearBorderDirectionCount(b)-1`.

static Direction nearBorderDirectionsCausal | ( | AtVolumeBorder | b,
|  | int | index |
| ) |  |  | `[static]`

The valid direction three codes in anti causal direction (means: look back in scanline direction)when the center is at the volume border. Should be used with isAtVolumeBorderCausal to determine the Directions, as this avoids using of the nonesense border ids (e.g. 0,1,8,9...) of this table. index must be in the range `0...nearBorderDirectionCount(b)-1`.

static Diff3D const relativeDiff | ( | Direction | fromCode,
|  | Direction | toCode |
| ) |  |  | `[static]`

Get the relative offset from one neighbor to the other. For example, `relativeDiff(East, West) == multi_differencetype(-2,0,0)`. (note: there is no bounds checking on the code you pass.)
